Hi Rajesh
it's no problem to use a stored proc, at least not if the DB is Oracle.
I have a descendent of JDBCAppender: myJDBCAppender. This class has a property PreparedSQL,
which is filled by the LogManager when initializing from configuration file (see below).
Within the overwritten execute method you must bind the ?-parameters to the passed values.
You get these values by parsing the sql-String which is passed by the caller of the method,
and which is the converted pattern. Therein are @@ used as delimiters of the values. Something
like that:
StringTokenizer tokenizer = new StringTokenizer( aSql, "@@" );
int i = 3;
while ( tokenizer.hasMoreTokens() )
{
String token = tokenizer.nextToken().trim();
switch ( i )
{
case 4 : // level. We have to convert the string into the level number
myCstmt.setInt( i, Level.toLevel( token ).toInt() );
break;
default :
myCstmt.setString( i, token );
break;
}
i++;
}
The definition in Log4J.xml:
<appender name="DB_APPENDER" class=".....myJDBCAppender">
<param name="PreparedSQL" value="{ ? = call INS_LOG( ?, ?, ?, ?, ?, ? ) }"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%F:%L@@%-5p@@%-10X{category}@@%-7t@@%m"/>
</layout>
....(filters)
</appender>
Hope this helps.
